Please address this concern prior to the decision due date of January 3l, <br />2000. <br />Monitoring Program Standards and Reporting: <br />After five quarters of data have been gathered from all of the monitoring points, this data is to be <br />submitted to the Division so that DMG may forth an opinion on numeric standards for the parameters <br />being monitored. After this standard has been set, if the Operator should find that these standards have <br />been exceeded in any sampling event, they should report the ezceedance to the Division immediately, so <br />that proper action may be taken, and provide the Division with a written report within five (5) working <br />days, when there is evidence of groundwater discharges exceeding applicable standards or permit <br />conditions imposed to protect groundwater quality. Please commit to this course of action. This is in <br />accordance with Rule 3.1.7(6) and (7) of the Construction Materials Rules and Regulations. <br />Please be advised that this technical revision may be deemed inadequate, and your application may be <br />denied on January 31 unless the adequacy items listed above are addressed to the satisfaction of the <br />Division. If you wish, you may request an extension the decision due date, to allow for more time to <br />resolve this issue. L` you have any further questions, please contact me at (303) 866-3567. <br />Sincerely, <br />Christina L. Kamnikar <br />Environmental Protection Specialist <br />Cc: Carl B. Mount, DMG <br />H.
